Lab 7 Wide Area Networks
7.1 Distance Consideration
7.1.1 A WAN is a wide area network that is often used by large businesses or corporations. It is impractical for an organization to own an entirety of a WAN because a WAN is decentralized
It’s l for an organization to own an entire LAN, or local area network, for business expansion purposes. This is control over a dedicated section of the local network that other businesses will want to buy into.
7.1.2 Increasing the required transmission distance of a signal will have a negative effect on the clearness of the signal. As the source is moved farther away from the receiver, a weaker signal will be present
7.1.3
UTP- summary (Short for unshielded twisted pair, a popular type of cable that consists of two …show more content…
unshielded wires twisted around each other. Due to its low cost, UTP cabling is used extensively for local-area networks (LANs) and telephone connections. UTP cabling does not offer as high bandwidth or as good protection from interference as coaxial or fiber optic cables, but it is less expensive and easier to work with
Coaxial-summary (RF connectors are typically used with coaxial cables and are designed to maintain the shielding that the coaxial design offers. Better models also minimize the change in transmission line impedance at the connection.
Fiber-optic /Infrastructure-secure cable systems( submarines)
Electric Power lines/ Infrastructure-overhead powerlines
7.2.4
Satellite-summary (is Internet access provided through communications satellites. Modern satellite Internet service is typically provided to users through geostationary satellites that can offer high data speeds,[2] with newer satellites using Ka band to achieve downstream data speeds up to 50 Mbps
WIMAX-summary (is a wireless communications standard designed to provide 30 to 40 megabit-per-second data rates
HSPA+-summary (is a technical standard for wireless, broadband telecommunication. HSPA+ enhances the widely used WCDMA (UMTS) based 3G networks with higher speeds for the end user that are comparable to the newer LTE networks. HSPA+ was first defined in the technical standard 3GPP release 7 and expanded further in later releases.
Radio Frequency-summary (is a rate of oscillation in the range of around 3 kHz to 300 GHz, which corresponds to the frequency of radio waves, and the alternating currents which carry radio signals. RF usually refers to electrical rather than mechanical oscillations; however, mechanical RF systems do exist (see mechanical filter and RF MEMS).
7.2 WAN connections
7.2.1 You don’t have to share your bandwidth with multiple users.
Cost and delay of installation are among the limitations.
7.2.2 Data can be transmitted from different devices simultaneously. This topology can withstand high traffic; even if one of the components fails there is always an alternative present. So data transfer doesn’t get affected and Expansion and modification in topology can be done without disrupting other nodes.
Geographical sites can appear on or in a full-mesh topology; the distribution layer allows the core layer to connect sites that run different protocols while.
7.2.3 Hub and spoke networks are well understood by all network administrators, and their benefits are thoroughly documented. They offer a high degree of security because each device on the network is isolated from the others through the single connection to the wireless router. Other benefits include high performance, centralization, and simplicity. They're relatively inexpensive and easy to wire and easy to fix if a component goes down.
It would not be a great choice because if the router dies then the network will go down, in a mesh, if one goes down another can pick up where the other went down.
7.2.4
T1-summary (is a digital circuit that uses the DS-1 (Digital Signaling level 1) signaling format to transmit voice/data over the PSTN network at 1.544 Mbps. T-1 can carry up to 24 uncompressed digital channels of 64 Kbps (DS0) for voice or data
T3-44.736 Mbps of total bandwidth and T3 lines are a common aggregation of 28 T1 circuits that yields 44.736 Mbps total network bandwidth.
E1-2.048 of total bandwidth
E3-summary (T3 lines are a common aggregation of 28 T1 circuits that yields 44.736 Mbps total network bandwidth.
